串列叶栅的尾迹平均速度和紊流脉动速度沿额线方向比单列叶栅变化平缓。
The mean wake velocity profiles behind tandem cascades satisfy the self-similarity, similar to that behind the single-row cascade.
串列叶栅的尾迹平均速度和紊流脉动速度沿额线方向比单列叶栅变化平缓。
Behind the tandem cascades, the variations of mean velocity and turbulence intensity along the tangential direction become more gentle than that behind the single-row cascade.
实验测量了射流与圆柱尾流纵、横向的湍流速度脉动，计算了这两种方向的湍流速度结构函数的标度规律。
The scaling of the longitudinal and transverse velocity structure functions is studied experimentally for turbulent jet and cylindrical wake flow.
